Description
Round-bottom flask with standard ground joint, LBG 3.3, NS 29/32, 2000 ml is a laboratory glass vessel intended for distillation, reflux, reaction and receiving work. It is produced from borosilicate glass 3.3 (LBG 3.3) and carries a nominal volume of 2 l together with a standardised ground joint of NS 29/32 for reliable connection to condensers, adapters and other jointed apparatus. The spherical body supports uniform heat distribution when used with heating mantles or baths and facilitates stirring and mixing of reaction mixtures. This flask from manufacturer Labbox belongs to the LBG product type and is supplied as a single piece with a net weight of 0,560 kg. Its material choice of borosilicate glass 3.3 is suited to everyday chemical handling where thermal and chemical resistance of this glass class is required. Typical laboratory roles include use as a round-bottom flask, ground-joint flask, distillation flask or receiving flask in preparative organic chemistry, solvent work-up and teaching laboratories. The NS 29/32 joint size ensures interchangeability within common European ground-joint systems, while the 2000 ml capacity addresses larger-scale batch and recovery tasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, LBG 3.3, mouth 29/32, 2000 ml
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 29/32, 2000 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
